Walking down a grocery store aisle can feel like a minefield when you have diabetes. Brightly colored boxes scream "All Natural," "Low Fat," or "No Sugar Added," but these marketing claims don't always tell the whole story and have little to no regulation in the food industry.
To truly understand how a food will affect your glucose, you have to flip the box over and look at the Nutrition Facts panel. This label is your roadmap. Once you know how to read it, you can stop guessing and start choosing with confidence.
Here are the three most important things to check before you put an item in your cart, and if you’d like a more detailed review of Nutrition Labels, check out the recorded webinar here:
Before you look at the sugar or carb count, look at the Serving Size. This is the single most common place where people get tripped up because a “Serving” isn’t the amount that makes you feel full. Instead, it is determined by the food company and is whatever they choose for that food product.
Every single number listed below the serving size (the calories, the carbs, the fiber) is based only on that specific amount. If the label says a serving is 1/2 cup, but you usually eat 1 cup, you have to double every number on that label.
Manufacturers often use "unrealistically small" serving sizes to make the calorie or sugar counts look lower. For example, a small bag of chips might actually contain two servings. If you eat the whole bag (which most of us do!), you’re getting twice the impact on your blood sugar than what you initially read.
The Strategy: Compare the serving size on the label to what you actually put in your bowl. If there’s a mismatch, do the math first.
If simple carbohydrates are the "gas" that makes blood sugar go up, fiber is the "brake pedal" that helps steady your blood sugar spikes. For patients with diabetes, fiber is your best friend for avoiding that "post-meal spike."
When looking at a label on carbohydrate foods like breads, cereals, or crackers, aim for at least 3 to 5 grams of fiber per serving.
Pro Tip: Look at the ingredient list. You want to see the word "Whole" (like whole wheat or whole oats) as the first ingredient. If it just says "Wheat Flour," the fiber has likely been stripped away and will not have the fiber benefits as outlined above.
Many people head straight for the "Added Sugars" line, but for diabetes management, the Total Carbohydrate count is the most important number. Total carbs include sugar, starch, and fiber. Since your body breaks both starches and sugars down into glucose, the "Total" gives you the most accurate picture of the insulin response required.
To keep your energy levels steady and your A1c in check, use these general benchmarks:
By capping your carbs at these levels, you prevent your body from being overwhelmed by a massive glucose load. It’s much easier for your body (and your medication) to manage 30 grams of carbs than 90 grams at a meal.
Note on "Sugar-Free": Don't be fooled by "Sugar-Free" cookies or candies. They often still contain high amounts of flour (starch) or sugar alcohols, which still contribute to the Total Carbohydrate count. Always check the total!
Mastering the label takes a few extra seconds in the aisle, but it saves you hours of frustration later when checking your blood sugar levels at home.
